UNITED STATES PATENT OFFICIa HAKON K. OLSEN, OF COALVILLE, UTAH TERRITORY.

SAWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 275,069, dated April 3, 1883. Application filed August 9, 1882. (No model.)

To all whom it may concern:

Be it known that I, HAKON K. OLsEN, of

Coalville, in the county of Summit and Territory of Utah, have invented a new and Improved Sawing-Machine, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a perspective view of my improved sawing-machine. Fig. 2 is a detail view of the feeding apparatus.

The object of my invention is to furnish an easy-working and rapid-cutting machine for felling trees and sawing logs into lengths.

Referring to the drawings, A is a frame, having a slot lengthwise through its center, containing a feed-screw, B. The frame A is pivoted at a to the upright post 0, and is capable of being turned either in a horizontal or vertical position by changing it on the pivot at a. On the screw B is placed a nut, B, to which a sleeve or guide,D,is rigidly attached at right angles with the screwB and the frame 0. Passing through the sleeve D is a sliding bar, E, whose outer end is widened and slotted and provided with a spring-bolt, b, for entering the hole in the end of the saw F. The inner end of the bar E is connected by a pivotjoint, 0, to the connecting-rod G, whose outer end is provided with a suitable box connecting it with the bar it of the adjustable crank H, the ends of the bar it being secured in holes 0 in the crank-arms H, the shafts of which are journaled in the movable blocks d d in the slotted leaning posts I I. The crank-arms H are provided with holes 0 at different distances for shortening or lengthening the stroke of the saw. At one end the shaft of the crank H is simply fitted to its box in the movable block d. At the opposite end it projects beyond the box, and is provided with a gear-wheel, e, to which the power is applied by a larger gearwheel, J. The gear-wheel J is fixed on the shaftf, which is journaled in the upper part of the movable boxes d d in the slotted posts I I. Near the end the straight shaftfis provided with a cone-pulley, g, which is connected with a like pulley, g, on the end of the screw 5 B by the belt 2'.

K is a Windlass journaled in the top of the leaning posts I I, and provided with ropesj j, fastened to the movable blocks 01 d, and running over pulleys k k k k, for the purpose of 5 raising or lowering andholding all the parts supported by the movable blocks 01 d, and to accommodate the driving mechanism to the position of the saw. The Windlass K is provided with arms K for operating it, and the arms are retained in position byapin,l,which enters a hole in the standard I.

This machine is light and portable, and may be handled and operated by one or more men, or by steam or other power applied by belt or 6 universal-jointed rods.

The frameA can be fastened either in a vertical or horizontal position by the clampingscrews M. It also can be set to saw at any angle. 7

When the saw is making a vertical or inclined out, it is detached from the feed-screw and feeds downward by its own gravity.

Two saws can be used by making the screw B with a right-hand screw} on one half and a 7 left-hand screw on the other hal i, so as to feed both saws inwardly toward the center of the tree.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 8 1. The combination, with the sliding sawcarrier E, of the sleeve D, the nut B, attached thereto, and the slotted frame A, pivoted to a post, 0, at a, as and for the purpose specified.

2. The combination, with the sliding saw- 8 carrier E, of the rod G, connected therewith by a pivot-joint, 0, the bar it, connected with said rod by a box, the crank-arms H, having holes 0, the movable blocks d, and the slotted posts I, the gear-wheel e on crank-shaft, and 9 the gear-wheel J on a shaft, f, connected with the screw B, whereby the saw-may be reciprocated and fed, as described.
